There was a toy contest a few years ago which I've won with a Nerf gun. I've also won with one in a "Maker Olympic". Since Nerf doesn't endorse modifying guns, I doubt they would sponsor a contest, I would love one though. It would be a nice motivation to get back into the hobby.

Considering the amount of contests I have won it may be hard to believe, but so far I've only held back one ible (Deadpool Knife Block), because I had hoped for a 3D printing contest (which started about two weeks later (it wasn't announced by the list)). Usually it is the other way around, I see a contest and remember a project I wanted to make in the past or finally document a project I had made (I always take pictures, I am just too busy/lazy to do the write-up since I usually rather start a new project).I use my drafts to remind me of project ideas, but very often they only consist of the title.Are you more interested in winning a prize or getting recognition?

In my experience the best way to get recognized is to tell people about what you've made, by contacting different websites or using social media. If you are interested in making money off of your ibles, you might consider affiliate links or sponsorships. This way not winning doesn't matter as much (especially if you've waited a long time to publish something).I just went through a few of your ibles and am impressed with what you are making, just a friendly hint: instructables with good pictures do a lot better in contest. Try adding at least one picture per step and make sure to use good lighting.

I'm sorry, I don't know what a M-88 is. If you are talking about real explosives, please take pictures ;-)

Thank you!

That would be cool. I wouldn't want to dissolve it though.

I agree, but I couldn't get my camera to focus on the bathing water, I somehow didn't think about using manual focus and figured the GoPro footage would be enough... I am pretty sure I will make an other batch, but I ran out of neon colours.

I am having the same issue with an instructable I am currently working on. The image from step 1 is shown on step 3 and all the other images aren't working. In the editor everything looks fine. The title is "Lord Vetinari Clock" (It is only halfway done so I don't want to share the link publicly yet).

Wow, beautiful work! As a hint, there is a list with upcoming contests (https://www.instructables.com/community/List-of-Upcoming-Contests/) and a "Make It Move" contest is starting really soon. I would suggest checking the list before publishing, since amazing things like this should have a pretty good chance of winning.

Is there a certain one you think should have won? I am not a staff member and rarely judge contests, but considering how many I have won, I might be able to help you. I browsed through a few of your projects and overall they are really good, so these suggestions are at a very high level and are definitely not meant to discourage you. Lighting and camera focus are key. Maybe you should consider getting a camera light. There were a few blurry pictures or the focus wasn’t on the area of interest, try taking lots of pictures of every step and discard the ones that aren’t nice. I sometimes take more than a hundred pictures for the title image playing around with positioning and lighting. A tripod is also very helpful.

I sometimes take more than a hundred pictures for the title image playing around with positioning and lighting. A tripod is also very helpful. Try leaving a bit of space around the object, so that it isn’t cut in your title image. Personally, I do not like having many image format changes and usually just stick to landscape. I think instructables that use only one format are a lot more pleasing to the eye. When going through an instructable, I prefer the ones that have only pictures taken by the author. I think so far I have only once used a stock image. Even though views aren’t a guaranty to win a contest, it certainly helps to have a successful instructable that has made it into the newsletter. In order to get into the newsletter you will need a lot of views in the first few days. I usually take a look at similar instructables or things I have made in the past and try to figure what websites wrote about it. Then I tell them that I have made something new and hope that they feature it on their site. I hope I didn’t offend you with my suggestions, like I said overall you are doing really well.

If you google for example "Deadpool Knife Block" or "Nerf Sentry Gun", you can see that a lot of websites wrote about my projects. So if I was going to build for example a new Sentry Gun I would go to a few of those and tell them about my new project.Btw. both of the projects got caught in the filters and it took a few day for them to get featured. So in the first few days they got hardly any views and weren't featured in the newsletter. Once other sites wrote about them and they were getting a lot of views (way more than other instructables at that time) I asked staff members why they weren't featured in the newsletter and they told me that they got overlooked. They were kind enough to put them in the newsletter and I ended up winning at lot of awesome prizes. I gu...

Thank you, I used about one roll of 750 g filament in total. I made two different versions of the middle though, since I didn't like my first design once it was printed. Overall the cost should be under $15.

Iwanted to add a boost function and a timer, but you can of course build ithowever it works best for you.

You are right, of course. Thanks a lot for your correction!

Yes, sorry. I decided to not publish a "stuff you need" list like I normally do, since I wanted people to read the whole Instructable before starting to build something that might harm them unless they take precautions.

In principle yes. However, I guess the amount of mold formed on the condenser of a climate control unit is much smaller than the one you described. Taking into account that you also have a lot of other surfaces the ozone can react with (tools, etc.) you would have to use a lot of ozone. I had exactly the same problem with my workshop and used a sodium hypochlorite based cleaner/bleach. The mold practically vanished into thin air after the first spray.

Hi! To my knowledge such oxygen generators use a membrane technique or an absorbtion/regeneration principle and are able to produce significantly more oxygen than my 20 g/h of ozone. I would, however, not expect too much of those "home" oxygen generators. At elevated levels of oxygen (~30%) humans develop signs of oxygen poisoning including vertigo and nausea... Personally, I would not like to sleep next to an oxygen generator.

I haven't tried it, but this is what their site saye:Can I embed a Screencast on my own webpage?Yes! When viewing a public or unlisted Screencast, there is an embed button. You will get a snippet of html code that you can paste into your own website. This will embed the Screencast, and viewers will be able to play the Screencast directly from your page, or follow a link to view it on the Screencast website.
